PHOENIX — Todd Helton has had enough.

Having decided earlier this year that this will be his final season, the Colorado Rockies decided to go public.

"I didn't want to say I was going to return and then come back in," Helton said before Sunday's game against Arizona. "I talked to my wife and thought about my body and mentally how I felt going out there for every game. I'm 40. It's time to go. It's a young man's game."
